IQ tests are often regarded as the best judge of intellectual capabilities. It should be noted, however, that an intelligence test score is merely a crude calculation of a person's intelligence. For instance, unlike weight or mass, the accurate amount of the intelligence of a person cannot be calculated as a result of the national nature of the idea of "intelligence". Regardless, an intellegence test is essential and should not be dismissed entirely. "IQ" is a popular lingo we all come across very often. It is an abbreviation for "intelligence quotient" which was coined by German psychologist William Stern for the German term "Intelligenzquotient". There are numerous interesting things about IQ which many people do not know. In this article, we will take a look at seven.

Facts About IQ Test Which You Probably Don't Know

1. IQ test has been around for more than a century

The idea of an IQ test is not modern. As far back as the late 1800s, the idea was already been worked on. English statistician Francis Galton was the first person to venture into the creation of a standardized test to rate a person's intelligence. However, he abandoned the research when he was not able to prove such a correlation exists. In the early 1900s, Alfred Binet, a French psychologist, together with Victor Henri and Théodore Simon successfully developed the first IQ test. It centered on verbal abilities and served as a medium to help fish out students who needed additional assistance in school.

2. Bighead equals high IQ?

Are people with big heads a lot smarter? Maybe or maybe not. There is an interesting divide among scientists as to whether head size has an impact on IQ. According to one study, people with larger heads were found to be less likely to experience a decline in their cognitive abilities in later years. However, another study revealed that there was not a strong correlation between brain size and IQ.

3. IQ increases with each generation

That is known as The Flynn effect, named after New Zealand political scientist James Flynn who documented and promoted awareness of this phenomenon. However, there is a debate on whether the rise in IQ test scores also represents an increase in overall intelligence or merely an increase in the skills connected to the test. For example, since kids nowadays go to school and are in sync with the testing of school-related material, it is reasonable to expect that they would perform better in areas such as language, mathematics, and general knowledge. Interestingly, in some countries, there is a reverse of The Flynn effect – a decline in IQ.

4. The highest IQ recorded is 210

Kim Ung-Yong, a professor from South Korea, holds the record as the person with the highest IQ in the world. Born in 1962, Kim's father was a physics professor, and his mother, a medical professor. By the age of five, he could speak five different languages – Korean, English, French, German and Japanese. He was invited to work for NASA when he was eight years old. Kim went on to work for 10 years but later described those years as very lonely, saying led his life like a machine.

5. U.S. military used IQ test to recruit in World War 

During World War I, leaders of U.S. armed forces needed a system that could quickly sort recruits into their ideal roles so they made use of an IQ test. American psychologist Robert Yerkes developed the intelligence test used to identify people capable of holding leadership positions, among other things. Literate recruits took the written Alpha test, while illiterate recruits took the visual Beta test

6. Albert Einstein did not take an IQ test

It is believed that German-born theoretical physicist, Albert Einstein had an IQ score of 160, the same as English theoretical physicist, Stephen William. However, what most people do not know is that it is merely an estimate. The renowned physicist whose ideas altered humanity’s conception of reality and led to numerous inventions never took an IQ test.

7. "Adults with low IQs should not procreate"

American psychologist, Henry Goddard postulated that adults with low IQs should procreate. Goddard, who was the first person to translate the original Binet intelligence French test to English in 1908, was the main advocate for using the intelligence test in societal institutions including hospitals, schools, the legal system, and the military. He also brought the term "moron" into clinical use. Goddard opined that people with low IQ should desist from having children. However, he did not push for mandatory castration – even though he believed that it would eliminate intellectual disability – because he was not sure if that suggestion would sit well with the majority of the public. Instead, he advised that people with low IQ should be segregated.
